Description
Technical field
The utility model relates to electrical equipment charging technique field, the charger of specifically a kind of long service life, band USB interface that power savings is good.
Background technology
As everyone knows, along with popularizing of portable type electronic products such as mobile phone, digital camera, MP3, to the also increase thereupon of demand of rechargeable battery; A large amount of uses of rechargeable battery have promoted also to the charger development of rechargeable battery charging and have improved that the most of alternating current that adopts of charger in the market changes into direct current, direct current is charged to needed electronic product again; Existing charger comprise the housing that has pin, be provided with transformer, voltage stabilizing circuit etc. in the housing, housing is exported a data wire; The connection-peg that the interface of the electrical equipment that the other end of data wire is provided with and is recharged matches does not particularly also have charger national standard today in China, and the socket of the charger of various electrical equipment is different; This not only causes great waste, returns the user carrying, using and make troubles, for overcoming above-mentioned deficiency; A kind of USB charger has been invented in the Dongguan City Yingju Electronics Co., Ltd, and the patent No. is 2009202368648, and it comprises housing; Housing is provided with the pin that can connect external power source, is positioned at the circuit board of housing, and the input of circuit board is electrically connected pin; Housing is provided with the USB maternal interface that can be connected with the data wire that has USB plug, and the output of circuit board is electrically connected the USB maternal interface, and housing is provided with LED light; LED light is electrically connected with circuit board, during use, the mobile phone connecting line is connected with charger through USB plug; The portable type electronic product such as mobile phone, digital camera, MP3 that can be different model charges; Have that general context is extensively wide, flexibility is high, easy to use, but its deficiency is when charging finishes, must charger and power supply be separated, otherwise interior speed changer and the indicator light on the housing of housing all is in operating state; This has not only wasted electric energy, also will influence the useful life of transformer, indicator light.
Summary of the invention
The utility model proposes the charger of the band USB interface of a kind of energy savings, long service life to the deficiency that exists in the prior art.
The utility model can reach through following measure.
A kind of charger with USB interface comprises housing, and housing is provided with pin, USB maternal interface and the LED light that connects external power source; Be provided with circuit board in the housing; The input of circuit board is electrically connected pin, and the output of circuit board is electrically connected USB maternal interface and LED light, it is characterized in that being provided with in the USB maternal interface button switching formula electric switch; Electric switch is electrically connected with the input of circuit board through lead
The fixed contact of the described electric switch of the utility model is electrically connected with pin through lead; The moving contact of electric switch is electrically connected with the input of circuit board through lead, when moving contact contacts with fixed contact, pin is connected with the input of circuit board; Transformer gets electric and the output low-voltage DC is electrical equipment and indicator light power supply; When moving contact separates with fixed contact, the input of pin and circuit board is separated, the transformer dead electricity is not worked.
The utlity model has that the structure structure is simple, easy to use, economical with materials and advantages such as the energy, long service life, particularly suitable is the charging of portable type electronic products such as mobile phone, digital camera, MP3.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Fig. 2 is the circuit block diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Shown in accompanying drawing, a kind of charger with USB interface comprises housing 1; Housing 1 is provided with pin 2, USB maternal interface 3 and the LED light 4 that connects external power source, is provided with circuit board 5 in the housing 1, and the input of circuit board 5 is electrically connected pin 2; The output of circuit board 5 is electrically connected USB maternal interface 3 and LED light 4, and the structure of above-mentioned each building block and connected mode are identical with prior art, and this does not give unnecessary details; The utility model is characterised in that and is provided with button switching formula electric switch 6 in the USB maternal interface 3, and electric switch 6 is accounted for spring by fixed contact, movable contact to be formed, and the structure of electric switch 6 and connected mode are identical with prior art; This does not give unnecessary details, and electric switch 6 is electrically connected through the input of lead with circuit board 5, and the fixed contact of described electric switch 6 is electrically connected with pin 2 through lead; The moving contact of electric switch 6 is electrically connected through the input of lead with circuit board 5, and electric switch 6 generally is located on USB maternal interface 3 inner faces, and the moving contact that the front end of USB pushes electric switch 6 contacts with fixed contact; Electric switch 6 also can be located on USB maternal interface 3 upper surfaces, lower surface or the side, and the connecting rod of moving contact takes the form of inclined plane, and the moving contact that in inserting the USB process, presses electric switch 6 contacts with fixed contact; When the utility model charges for electrical equipment when needs; USB plug is inserted in the USB maternal interface 3, and USB plug pushes away (pressure) electric switch 6 makes moving contact contact with fixed contact, and this moment, pin was connected with the input of circuit board; Transformer gets electric and the output low-voltage DC is electrical equipment and indicator light power supply; When extracting USB plug, under the effect of electric switch spring, when moving contact separates with fixed contact; This moment, the input of pin and circuit board was separated; The transformer dead electricity is not worked, above-mentioned button switching formula electric switch 6 the utlity model has that the structure structure is simple, easy to use, economical with materials and advantages such as the energy, long service life, particularly suitable is the charging of portable type electronic products such as mobile phone, digital camera, MP3.
